As the guy who wrote the SMTC stuff, I'd recommend picking up something
newer. Ralf has merged some of the subsequent improvements and fixes
into 2.6.18, but not the patches that I made last year to allow tickless
support, which is actually a very, very good thing to have for SMTC.
That support was initially available in 2.6.24, but subsequently got
broken by some changes to control register manipulation APIs that I
identified and fixed a few months ago. Ralf back-merged them into
several recent baselines, but I'm not sure which ones. 2.6.29-stable
seems to have all the right patches applied for SMTC, but of course I
can't tell whether there would be other issues for your platform.

Could any of you suggest me in which way i have to proceed?. Does it
make sense to continue using 2.6.18 or port newer kernel version (
which might be having better SMTC/SMP support)?
